88.5 mol of p4o10 contains how many moles of p?

Answer : The number of moles of phosphorous are 354 moles.

Explanation :

The formula of given compound is,

In compound, there 4 moles of phosphorus and 10 moles of oxygen.

As we are given that the moles of is 88.5 mole. Now we have to determine the number of moles of phosphorous (P).

As, 1 mole of has 4 moles of phosphorous

So, 88.5 mole of has of phosphorous

Therefore, the number of moles of phosphorous are 354 moles.

c- cold periods in earth's history during which glaciers covered much of the surface.

explanation:

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
